GLIF VisionGLIF Vision

Linking the World with Light

• Optical networks are the central architectural element in support of this decade’s most demanding e-science applications.

• Research should not have any geographical boundaries.

• Hybrid networks are the next-generation networks:

• Packet-switched Internet for regular many-to-many usage

• Dedicated lightpaths for guaranteed high-speed few-to-few usage.

What is GLIF?What is GLIF?

• Established in August 2003 at 3rd LambdaGrid Workshop in Reykjavik.

• International virtual organisation to promote and support optical networking

• Collaborative initiative of worldwide NRENs, institutions and consortia working with lambdas.

• Provides a global-scale laboratory to facilitate application and middleware development, and to build distributed systems.

• A forum for making contacts, exchanging information and experiences, and resolving technical problems.

• Working towards harmonisation of policy, service and fault management processes.

GLIF OrganisationGLIF Organisation

• Open to any organisation sharing vision of optical interconnection of different facilities, who voluntarily contribute network resources (e.g. equipment, lambdas) or actively participate in relevant activities.

• Managed as cooperative activity with ‘participants’ rather than ‘members’.

• Participants operate under lightweight governance structure.

• Secretariat functions provided by TERENA with contributions from sponsors.

• Currently 42 members (see http://www.glif.is/participants/).

GLIF Open Lightpath Exchanges (GOLEs)GLIF Open Lightpath Exchanges (GOLEs)

• GLIF lambdas are interconnected through established exchange points known as GOLEs.

• GOLEs are comprised of equipment capable of terminating lambdas and performing lightpath switching, allowing end-to-end connections (e.g. Nortel HDXc, Cisco ONS 15454).

• Open connection policy (i.e. no restriction on interconnection with commercial networks) and interconnect at least two autonomous optical domains.

• Coordination effort to document resources, set-up and tear-down connections, troubleshoot, and establish common policies. Monthly teleconferences improving liaison.

• Established GOLEs:• CANARIE-StarLight, Chicago (CANARIE)• CANARIE-PNWGP, Seattle (CANARIE)• CERN, Switzerland (CERN)• KRLight, Seoul (KISTI)• MAN LAN, New York (Internet2, NYSERNET, Indiana University & IEEAF)• NetherLight, Amsterdam (SURFnet)• NorthernLight, Stockholm (NORDUnet)• Pacific Northwest GigaPoP, Seattle (Consortium of research and education organisations)• StarLight, Chicago (UIC/EVL, NWU/iCAIR & Argonne)• T-LEX, Tokyo (WIDE)• UKLight, London (UKERNA)• UltraLight, Los Angeles (Caltech/NSF)
